SojaLin Thank you for the detailed information about your system.
Since other users working with the same Spine project are not experiencing this issue, it is possible that the behavior is related to your specific system environment rather than the editor version itself.
Given that the slowdown becomes more noticeable after working for some time, one potential cause could be background software activity. In particular, real time antivirus scanning can sometimes cause significant delays when applications access files, load assets, or open menus. This may result in temporary freezing or long pauses similar to what you described.
As a troubleshooting step, we recommend checking the following:
- Temporarily disable real time antivirus scanning and test whether the issue persists.
- Add the Spine installation folder and your project folder to the antivirus exclusion list.
- Close any unnecessary background applications, especially screen recording software, cloud sync services, or overlay utilities.
- Monitor memory usage in Task Manager while the slowdown occurs, to see whether memory consumption is approaching a limit.
If the issue improves after disabling antivirus scanning or excluding the relevant folders, that would strongly suggest an environmental cause.
